Abstract

Jasmine flowers Uasminum sambac) had very low contents of essential oil and were extremely delicate, heating them would destroy the blossoms before releasing the essential oils. In such cases, enfleurage was sometimes used to remove the essential oils. Jasmine flowers were placed on solid fat, which will abso.b the flowers' essential oils. When all the fragrance was transferred from the flowers to the fat they were removed and replaced with fresh ones. This process was repeated several times until the fat becomes saturated with the essential oil (pomade). The extrait extracted by alcohol from pomade, and then absolute jasmine oil separated from alcohol used rotary vacuum evaporator. The objective of this research was to enfleuragejasmine oil with shortening (snow white) at severall frequency of jasmine flower subtitutions by using completely randomized design. The treatments were Al = two frequency, A2 = four frequency, A3 = six frequency,A4 = eight frequency, AS = ten frequency. Results showed that the treatments very significant (p<0.01) affected the rendement, but not signifficant affected the melting point, spesific grafity and refraction index. The highest rendement (0.287%) was obtained from four frequency (A2). The charateristic of jasmine oil were melting point l6.3°C, specific grafity 0.942 and refraction index I. 480.
